Capacity and form factor

This NEMIX RAM module provides 4GB of DDR4 memory in a 260-pin SODIMM package. It targets laptops, all-in-one PCs, small-form-factor desktops and NAS devices that accept non-ECC unbuffered memory. The single-rank design uses CL19 timings at the standard 1.2V operating voltage.

Speed headroom and limits

Rated at DDR4 2666 (PC4-21300), the stick delivers mainstream bandwidth for everyday multitasking and office workloads. Capacity tops out at 4GB, so memory-intensive tasks such as virtualisation, heavy rendering or large databases will exhaust the available space quickly. The CL19 latency is adequate for the rated frequency but offers no overclocking margin.

Thermals and power draw

With no heat spreader fitted, the module relies on the host device’s internal airflow for cooling. At 1.2V the power draw remains low, keeping thermal output minimal during typical workloads. The unbuffered, non-ECC design adds negligible electrical load, so fan noise and system temperatures stay essentially unchanged after installation.

Questions about this item

Will this DDR4 2666 CL19 SODIMM work alongside my existing DDR4 memory?

This module runs at DDR4 2666 with CL19 latency and 1.20V voltage. Mixing speeds or timings may cause the system to run at the lowest common settings.

How can I verify the 4GB module is recognised at the correct speed after installation?

Check the BIOS or use a system information tool to confirm the memory shows as 4GB DDR4 2666 (PC4-21300) with CL19 timings at 1.20V.

Does the MS21300-416K1 package include only the SODIMM or are tools or adapters supplied?

The package contains the single 260-pin SODIMM module only; no tools, adapters or additional components are included.
